In situ NMR study of hydrogenation/dehydrogenation of ZrCr2 and physisorbed hydrogen

Study on Hydrogen Storage Properties, Anti-Oxide Ability and Rate Limiting Step of ZrCr-Based Alloy after Introducing Cobalt as Additive

“…We directly carried out the first hydrogen absorption process under mild experimental conditions. Table 2 shows the conditions needed before the first hydrogenation of different Zr-Cr alloys in previous studies [8,10,14,[16][17][18][19]26,30,[32][33][34]. The high temperature (573∼850 K) and prior hydrogen exposure (∼3 MPa) were needed to activate the Zr-Cr alloys in most previous studies.…”

“…Recently, Bodega et al [18] synthesized ZrCr 2 laves phases and investigated the thermodynamic stability of their hydrides. Ahmad et al [19] used the in-situ NMR technology to study the hydrogenation and dehydrogenation of ZrCr 2 alloy. Erika et al [10] got ZrCr 1−x NiMo x alloys to systematically investigate its electrochemical and metallurgical characterization.…”

A new sample preparation method for WD-XRF analysis of sulfide ores by fusion techniques: a BN crucible for protection against contamination and quantitative retention of sulfur

“…In recent years, a boron nitride (BN) crucible has been used for analysis. [17][18][19] It is advantageous as it maintains stability at 900 C in air. Furthermore, its constituent elements are B and N; hence, it can be used for analysis as it is devoid of any sulde.…”
